It'd help a lot if you told us what kind of music you play. A good way to incorporate arpeggios into your playing is to quickly get you from the root of one chord to another. I play double-bass in a jazz band, and when I'm walking between chords, if I find myself far away from the next root, instead of using scale tones to try to get there, I'll throw in an arpeggio. And as equator was saying, try using some different arps, not just major or minor. I can give you some specific examples if you like.
